Chromatic adaptation matrix from arbitrary color temperature to arbitrary/standard.

[ssh4net]

Hello!

Can someone point me to a right way to compute chromatic adaptation matrix from arbitrary WB color to another or standard like D50/D55/D65?

For example I have measured white point inside stage and need use that value to adapt colors to standard WB in transform data between color spaces.

And can spectral measure (I have Sekonic C-800) give me more valuable information for such tasks than estimated White Point in kelvins?

Thank you.

Hi Vlad,

The colour.adaptation.matrix_chromatic_adaptation_VonKries takes two CIE XYZ tristimulus values which are the test and reference tristimulus values to produce the adaptation matrix.

Cheers,
